We needed a new air cleaner & a new central air conditioning system in our house, then my good friend and I have consistently had a nice HEPA air filter running in our house, & it never presented any problems for us.
The same goes for our central air conditioning system.
My good friend and I live in a truly hot weather conditions, so a central air conditioning system is essential to our everyday life, then when my friend and I purchased our home, my friend and I made sure my friend and I chose the best central air conditioning system my friend and I could find to ensure it was a good quality central air conditioning system. My good friend and I shopped at at least seven different heating & cooling businesses searching for the right central air conditioning system until my friend and I finally found the one. My good friend and I have an Heating & Air Conditioning company come over & inspect our central air conditioning system, heater, & HEPA air cleaner every two months, so my friend and I were truly surprised when our central air conditioning system & HEPA air filter stopped working. At first my friend and I thought that maybe there was some kind of a fuse blown, or maybe one of our small children messed with the smart thermostat, but after checking all the fuses, & making sure the smart thermostat was set respectfully, our central air conditioning system & HEPA air cleaner were still not working. My good friend and I called the heating & cooling company & hired a professional Heating & Air Conditioning company to come over & repair both of our broken Heating & Air Conditioning units for us. Apparently the central air conditioning system just had a clogged air filter which was a truly self-explanatory fix, but the HEPA air cleaner had some other underlying problems that the Heating & Air Conditioning company said would take some time to repair.
